app4cam has released an updated version of its 'gps4cam' iPhone app that allows users to geotag images from any digital cameras even when their phone doesn't have a signal. The app logs the location details as users travel around, then creates a QR-Code that allows this data to be easily synchronized with photos using the associated 'gps4cam Desktop' PC or Mac software. The gps4cam app can be downloaded from Apple’s App Store for $1.99.
